JIS Middle School uses a four day rotational calendar. We have Blue & Blue* days and White & White* days. All classes on blue/blue* days are the same but afternoon and morning classes flip. This is the same for white/white* days. This means that students will have all of their classes every two days. This also means there is a rotation for which classes happen first block in the morning and last block. This evens out the learning attention for all classes.
